Heat Pumps

Heat Pumps Manassas, VA

If your home’s HVAC set-up includes a heat pump, you know what it’s like to save energy while enjoying even, comfortable temperatures. But heat pumps are not just for cooler months. They also provide high-efficiency cooling when the weather warms up—and they control indoor humidity for optimal year-round comfort. Trust Parrish Services to install, replace, repair or maintain your high-efficiency VA heat pump

Unlike furnaces and traditional HVAC equipment, heat pumps don’t burn fuel to generate heat. Instead, they use refrigeration technology to achieve your climate goals. In warm weather, circulating refrigerant captures indoor heat and exhausts it outside. During winter, the process is reversed. Heat is extracted from outdoor air and used to warm your home.

Cooling efficiency is measured with seasonal energy efficiency ratios (SEER). In climates where heat pumps are used mostly for cooling, higher SEER ratings are preferred. For cold weather use, a higher heating seasonal performance factor (HSPF) is recommended. Heat pumps work best in temperate climates without drastic temperature swings, but many Northern VA residents find these devices quite effective for supplemental heating.

Heat pump services in Manassas with an ENERGY STAR rating have a SEER of 18 to 27.5 and an HSPF of 8.5 to 12.5. While these units cost more upfront than other heating devices, their superior efficiency is often worth the expense. For economy and value, the American Council for an Energy-Efficient Economy (ACEEE) recommends buying a heat pump with a SEER of 15 or greater and a minimum HSPF of 8.5.

Common Home Heat Pump Systems

Follow these tips to get the best heat pump performance:

  • Set the thermostat and forget it. A heat pump maintains even temperatures as it switches back and forth from heating to cooling. Northern VA residents usually require a backup heating source when temperatures drop below freezing.
  • Perform seasonal maintenance twice per year, before and after the cooling season.
  • Consult a professional to be sure heat pumps and other HVAC equipment is properly sized for your Northern VA home.
  • Clean heat pump filters frequently and clear debris from outside condensing units.

Just a standard maintenance evaluation on my HVAC system but my tech was on time, polite, thorough and knowledgeable. He advised me on parts I can replace myself to buy a little more time with my current older unit rather than trying to upsell me. He advised that I will likely need a new unit in the next couple of years, but again did so without any pressure to address prematurely. Overall it was great exchange and established a sense of honest trade work. This will not be forgotten when it is time to buy a new system!

This was our 1st annual check up. Robert was very helpful and professional. However, we found the prices to be very high. We’ll have to really consider the recommendations.

When your air conditioner goes out, and it's July...the hottest month of the year...it's an emergency! So I took the first appointment I could get with a company that used a bait and switch technique of leading me to believe they could come soon- only to later confess they would have to come later. I kept calling around and got someone at Parrish Services. They were honest about what they could and could not do. They sent out true professionals who diagnosed the problem within 10 minutes...fixed it, and spoke honestly about what they were doing and what to look out for in the future! Thank you Parrish Services!!

I have had a service contract with Parrish Services for many years. Everyone now and again I get pleasantly surprised with service for an issue that is most unpleasant.I had my semi-annual service check done 2 weeks ago. Over the past 2 days it's been warm in the house. I called Parrish to come back to look at the A/C system again. In a matter of 2 hours they were able to schedule next-day service, and the tech re-arranged his calls for service so that he spent less time driving. That meant I was next on his schedule based on location of service calls.The tech ended up locating a major coolant leak. We opted for the lesser of two expenses by having the coil replaced (a quarter of the price of a brand new unit; still not cheap, but better than replacing the entire unit).I am thankful for Parrish Services' scheduling diligence and courteous service. They bent over backwards to schedule a next-day appointment during a stretch of the year when they have an overabundance of A/C service calls.
